我国首创的以水蒸汽为脱附剂的分子筛脱蜡过程,经过十多年的运转,得到了进一步完善和发展。这个过程能够发展的关键之一,在于使用了一种抗高温水蒸气的、以硅酸铝凝胶(以下简称硅铝胶)为粘合剂的脱蜡5A 分子筛。因此,这种硅铝胶粘合剂也就成为以水蒸气为脱附剂的分子筛脱蜡工艺的基石之一。本文就这一问题作概括性的论述。

China’s first molecular sieve dewaxing process using water vapor as a desorbent, after more than 10 years of operation, has been further improved and developed. One of the keys to the development of this process is the use of a dewaxed 5A molecular sieve with a silicate gel (Silica gel) as a binder against high temperature water vapor. As a result, the aluminosilicate adhesive has also become one of the cornerstones of the molecular sieve dewaxing process using steam as a desorbent. This article gives a general discussion of this issue.
